When I meant he wasn't the biggest star in the Telugu industry, I meant before Bahubali.
Yes today he is. But that's after Bahubali released. If instead of Prabhas Allu Arjun or NTR or Ram Charan played Bahubali, then even they would have gotten the similar level of stardom and would have been offered these Pan India films.
And regarding Saaho, it was a huge film set on a huge canvas. I think the first look of the film was released after BB2 released. The hype was insane. And the trailer received unanimous response. Add the goodwill he received from Bahubali gave it that huge first day.
But to say that he will challenge the big 6 Bollywood stars who have been in the industry for the last 30 years and say he will be bigger than them in few years isn't going to happen anytime soon.
Let him do a smaller scale film like Mirchi or Rebel and dub that film and release it in Hindi. If that film also gets a 24cr opening day, then we can talk about his stardom.
Even I am excited for Adipurush and can be a huge grosser across India, but to talk about having a stardom matching the other Bollywood actors is a topic for another day.
